Chilly cathode gauges are precise from 10−two Torr to ten−9 Torr. Ionization gauge calibration is rather delicate to construction geometry, chemical composition of gases remaining calculated, corrosion and surface deposits. Their calibration may be invalidated by activation at atmospheric pressure or minimal vacuum.
